After 30 years of asking those questions and testing and using nearly everything from Minox, 16mm, 35mm, 6x6cm, 6x9cm, 4x5in and 8x10in I have settled on a simple realization that larger format cameras make better big prints. Likewise, small prints, like 4"x5" don't benefit from a big camera. I have even done 8x10in to 4x5in reductions to test that.
